The Lexus LFA is a 2-seat “supercar” and is the second model vehicle in the F marque line of performance vehicles from the carmaker Lexus. There have been three different concept versions of this vehicle shown and each of them have debuted at the North American International Auto Show. Development of this vehicle initially began in the early 2000s when the very first LF-A concept car was introduced to the public in 2005 and then another one later on in 2007. The production version of the Lexus LFA uses a new V10 engine as well as a carbon fiber-reinforced polymer CFRP body.
The Lexus LFA uses a 72-degree bank angle 4.8 liter V10 engine which is equipped with dual VVT-i and carries the 1LT-GUE designation with a maximum output of 412 kW or 560 PS and delivers a total of 8,700 rpm with 354 pound-feet of torque. This engine redlines at 9,000 rpm but has a fuel cutoff which is set at 9,500 rpm and is built is forged aluminum pistons as well as forged titanium connecting rods for a truly durable setup. The LFA’s V-10 engine has a V-angle of 72 degrees in order to completely balance the firing force from the pistons inside.
The gearbox inside this vehicle is a 6-speed automated sequential gearbox or electrohydraulic transmission operated with paddle shifters. The chassis that the Lexus LFA is built on is made from carbon fiber-reinforced polymer center monocoque and features aluminum front and rear subframes. These subframes can be removed and replaced, keeping repair costs at a bare minimum. The quality of the CRFP materials has been claimed to be the same as the kind that is used in aeronautic engineering.
There is also an electric power steering rack in this vehicle which has a 14:3:1 gear ratio. The front suspension in the LFA uses a double wishbone arrangement as well as a multi-link arrangement at the rear with coil-over damper for every wheel. A rear transaxle is used on this vehicle in order to maintain ideal weight distribution. The windshield washer reservoir on this vehicle is mounted in the center close to the fuel tank, which is another design feature that was done to reduce overall weight. As far as the exterior of this vehicle is concerned, the LFA measured 4,506 mm or 177.4” in length. This vehicle’s wheelbase measures 2,606 mm or 102.6” as well as a height of 1,219 mm or 48” and a width of 1,895 mm or 74.6”.
The interior of this vehicle features a combination of materials, including alcantara, leather, carbon fiber, and metallic surfaces throughout. There are also two bucket seats as well as a Lexus’ Remote Touch controller interface. The interior design for this vehicle utilizes bespoke materials and colors, giving it a stylish overall look. The instrument display for this vehicle is a digital thin-film transistor speedometer with color-changing background as well as size-changing numbers and side-appearing submenus.
The Lexus LFA has won numerous awards and was named Road & Truck’s Best of the 2009 Tokyo Auto Show. The Evo UK also won “best engine of the year” in January of 2011. The 4.8 liter V10 which this vehicle uses was rated the “best engine of the year”, beating out the SLS AMG’s V8 as well as a number of other competitors. The initial reception of this vehicle by the public was impressive at first and it continues to be a very popular car in numerous markets around the world. Perhaps the most impressive thing about this vehicle is the innovative designs of the engines it has used over the years and continues to be an innovative force in the automotive industry.
